OIL AND/R REAGENT FEEDER Application filed. August 6, 193( .SerialNo. 473,494.

This invention relates to improvements in oil and/or reagent feeders.

The principal object of this invention is to produce a device wherein a given quantity of oil or other commodity may be fed therethrough.

Another object of the invention is to produce a device wherein the danger of clogging is reduced to a minimum.

A further object is to produce a device wherein easy adjustment may be accomplished while the device is in operation.

A still further object is to produce a device which is economical to manufacture.

Other objects and advantages will be apparent during the course of the following description. 7

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designated like parts throughout the same,

Figure 1 is a side elevation of my device,

Figure 2 is an enlarged fragmentary detail view showing the valve arrangement,

Figure 3 is a cross sectional view taken on the line 33 of Figure 1, and

Figure 4 is a top plan view showing the shape of the pusher button.

In the oil floatation process wherein ore is recovered from crushed material passed over floatation cells it is essential that a certain definite quantity of oil be admitted to the cells in order to accomplish a perfect separation. Applicant has therefore devised a accomplished.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5' designates a frame-work upon the upper portion of which is supported a tank 6. This tank is connected by a pipe 7 to a shut-ofl' valve 8 which valve is connected by a pipe 9 to a reservoir 11 which reservoir has a valve seat 13 adjustably positioned therein. This valve seat is adapted to be contacted by a valve 14: formed upon a rod 16 to which a cup 17 is attached through the medium of nuts 18 and 19. This rod 16 passes down- 5 ward and carries a pusher button 21 upon its very simple mechanism wherein this may be lower end. An adjusting nut 22 is threaded upon the rod and a spring 23 is interposed between the nut 22 and a cross member 24. A pivoted lever 26 underlies the nut 22 and the position of this lever may be regulated by a thumb nut 27.

A cam 28 carried upon the shaft 29 is adapted to rotate beneath the pusher button 21 so as to raise and lower the rod 16, the amount of raising and lowering being controlled by the position of the lever 26. In order to prevent the rod 16 from rotating, the nut 21 is of the shape shown in Figure 4 and passes through a plate 31 carried upon the underside of the cross bar 32. A spout 33 is formed upon the cup 17 and is the means for discharging the oil from the device from the floatation cells.

In operation the device works as follows Oil is placed in the storage tank 6 and:

when the valve 8 is opened this oil will pass into the reservoir 11 so that as the shaft 29 rotates the cam 28 pushing upon the pusher button 21 will move the rod 16 upwardly thus lifting the valve 14 from its seat 13. As soon as the cam is passed from beneath the pusher button 21 the spring 23 together with the gravity will cause the rod 16 to move downwardly thus seatingthe valve 14 upon its seat 13. At each movement of the valve from its 1 seat a certain quantity of oil will flow into the cup 17 and assuming that the cup is filled this flow will move out through the spout 33 and will then discharge into the floatation cell. stream of oil, the lever 26 may be adjusted so as to prevent the rod moving entirely down thus holding the valve 14 off its seat.

It will thus be seen that I can regulate the flow of oil from a single drop to a steady stream with a very economical apparatus.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative tothe' material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

When it is desired to have a steady Having thus described my invention, I claim An oil distributing mechanism comprising a tank, a receptacle positioned beneath said tank, a cup beneath said receptacle, a valve interposed between said receptacle and said 0111)., 1'1163115 for actuating said valve said means. i tl-i d s a qi q ed ma l. va v and to said cup and having a pusher button formed thereon, a cam adapted to engage said pusher button, and means for limiting the downward stroke of said rod for the purpose specified.
